Property

O.DropTarget#dropAcceptedDataTypes

Object

An object mapping data types the drop target can handle to a truthy
value.

dropAcceptedDataTypes: {},

Method

O.DropTarget#willAcceptDrag( drag )

When a drag moves over the drop target, this method will be called to
determine whether the target is willing to accept the drag. If it
returns true, it will become the active drop target. If it returns
false, it will be ignored, and any parent views which are drop targets
will be considered instead.

Unless overridden, this method simply checks whether any of the data
types available in the drag are included in its dropAcceptedDataTypes
property.
